Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8370, here are decompositions:

7 + 8363 = 8370
17 + 8353 = 8370
41 + 8329 = 8370
53 + 8317 = 8370
59 + 8311 = 8370
73 + 8297 = 8370
79 + 8291 = 8370
83 + 8287 = 8370

Showing the first eight; more decompositions exist.
